Abstract: In May 2010, the Coalition Government, by the Conservative Party and Liberal Democrat Party, came into power, and some changes were also made on the climate change policies accordingly. This paper is trying to find some emphases and changes of UK’s climate change policies, based on the Annual Energy Statement announced by the Coalition Government on July 27, 2010, the article published by Prime Minister David Cameron, and the speech delivered by Energy and Climate Change Minister Chris Huhne. The new government promotes international emission reduction and maintains the international business interests of UK’s low-carbon technologies. The new government requires major developing countries to commit to the mitigation actions which are measureable, reportable and verifiable. The UK’s government shifts the focus of domestic climate change policy from emission reduction to adaptation. The new British government attaches great importance to China in the low carbon technology cooperation. Facing new opportunities as well as challenges, China needs to develop a low-carbon development strategy at national level as soon as possible.
